VA9208-GGx-x Series Proportional Electric Spring Return Valve Actuators Installation

Instructions 1

Refer to the QuickLIT website for the most up-to-date version of this document.

Applications

The VA9208-GGx-x Series Proportional Electric Spring

Return Actuators are direct-mount valve actuators that

operate onAC/DC 24 V power. These bidirectional

actuators are used to provide accurate positioning on

Johnson Controls® VG1000 Series 1-1/4, 1-1/2, and

2 in. (DN32, DN40, and DN50), ball valves in Heating,

Ventilating, and Air Conditioning (HVAC) applications.

Integral line voltage auxiliary switches, available only

on the VA9208-xxC-3 models, indicate end-stop

position, or perform switching functions within the

selected rotation range.

VA9208-GGA-2 actuators include plenum-rated cables

and are specially configured for installation in spaces

used for environmental air-handling purposes other

than ducts and plenums as specified in National Fire

Protection Association (NFPA) 70: National Electrical

Code section 300.22(C), Other Space Used for

Environmental Air. The space over a hung ceiling used

for environmental air handling purposes is an example

of the type of space for which these actuators are

configured.

Installation

Install the ball valve with the actuator at or above the

center line of the horizontal piping (see Figure 1).

IMPORTANT: Use this VA9208-GGx-x Series

Proportional Electric Spring Return Actuator only to

control equipment under normal operating

conditions. Where failure or malfunction of the

electric actuator could lead to personal injury or

property damage to the controlled equipment or

other property, additional precautions must be

designed into the control system. Incorporate and

maintain other devices, such as supervisory or

alarm systems or safety or limit controls, intended to

warn of or protect against failure or malfunction of

the electric actuator.

IMPORTANT : Utiliser ce VA9208-GGx-x Series

Proportional Electric Spring Return Actuator

uniquement pour commander des équipements

dans des conditions normales de fonctionnement.

Lorsqu'une défaillance ou un dysfonctionnement du

electric actuator risque de provoquer des blessures

ou d'endommager l'équipement contrôlé ou un autre

équipement, la conception du système de contrôle

doit intégrer des dispositifs de protection

supplémentaires. Veiller dans ce cas à intégrer de

façon permanente d'autres dispositifs, tels que des

systèmes de supervision ou d'alarme, ou des

dispositifs de sécurité ou de limitation, ayant une

fonction d'avertissement ou de protection en cas de

défaillance ou de dysfonctionnement du electric

actuator.

IMPORTANT: In steam applications, install the

valve with the stem horizontal to the piping. Failure

to follow this precaution may shorten the life of the

actuator.

IMPORTANT: Before specifying VA9208-GGx-x

Series Actuators for plenum applications, verify

acceptance of exposed plastic materials in plenum

areas with the local building authority. Building

codes for plenum requirements vary by location.

Some local building authorities accept compliance to

UL 1995, Heating and Cooling Equipment, while

others use different acceptance criteria.

IMPORTANT: Do not install or use this actuator in

or near environments where corrosive substances or

vapors could be present. Exposure of the actuator to

corrosive environments may damage the device’s

internal components, and will void the warranty.

Mounting the Thermal Barrier

Figure 16 shows the optional M9000-561 Thermal

Barrier.

To mount the optional thermal barrier:

1. Install the thermal barrier drive shaft into the

thermal barrier by aligning the tab on the drive

shaft with the slot on the thermal barrier

(Figure 17).

2. Rotate the drive shaft to align marks on the top of

the thermal drive shaft with matching marks on the

valve stem.

3. Mount the thermal barrier onto the valve using the

four included M5x16 mm machine screws and four

M5 flange nuts. Tighten the screws to a

recommended torque of 21 to 25 lb·in.

(2.4 to 2.8 N·m).(Figure 18).

4. Proceed to actuator mounting instructions. Follow

the same steps as mounting directly to the valve

when mounting the actuator to the thermal barrier.

Manual Override

Use only the supplied manual override crank to

reposition the actuator hub when using the manual

override feature.

To reposition the actuator hub, proceed as follows:

1. De-energize the actuator.

2. Insert the hex end of the manual override crank

into the manual override adjustment point on the

face of the actuator.

3. Rotate the manual override crank in the direction

indicated by the arrow on the label.

with a power tool may damage the internal

components of the actuator and cause premature

failure.

4. The actuator requires 8-1/2 manual override crank

rotations from the full spring return position to fully

reposition the actuator hub.At the end of travel, the

rotation resistance increases. Do not force the

manual crank past this point.

5. While holding the manual crank in the wound

position, rotate and hold the red lock shaft

approximately 10° then release the manual crank

to lock the actuator hub in place.

Note: Insert and slightly rotate the manual crank

in the direction indicated by the arrow on the label

to unlock the actuator hub.Alternately, the actuator

hub automatically unlocks when power is applied

to the actuator, and returns the actuator to normal

drive and spring return operation.

Wiring

WARNING: Risk of Electric Shock.

Disconnect or isolate all power supplies

before making electrical connections.

More than one disconnection or isolation

may be required to completely

de-energize equipment. Contact with

components carrying hazardous voltage

can cause electric shock and may result

in severe personal injury or death.

AVERTISSEMENT : Risque de

décharge électrique.

Débrancher ou isoler toute alimentation

avant de réaliser un raccordement

électrique. Plusieurs isolations et

débranchements sont peut-être

nécessaires pour -couper entièrement

l'alimentation de l'équipement. Tout

contact avec des composants porteurs

de tensions dangereuses risque

d'entraîner une décharge électrique et de

provoquer des blessures graves, voire

mortelles.

CAUTION: Risk of Property Damage.

Do not apply power to the system before

checking all wiring connections. Short

circuited or improperly connected wires

may result in permanent damage to the

equipment.

MISE EN GARDE : Risque de dégâts

matériels.

Ne pas mettre le système sous tension

avant d'avoir vérifié tous les raccords de

câblage. Des fils formant un court-circuit

ou connectés de façon incorrecte

risquent d'endommager

irrémédiablement l'équipement.

CAUTION: Risk of Property Damage.

Insulate and secure each unused wire

lead before applying power to the

actuator. Failure to insulate and secure

each unused wire lead may result in

property damage.

MISE EN GARDE : Risque de dégâts

matériels.

Isoler et protéger chaque fil non utilisé

avant de mettre l'actuator sous tension.

Le non-respect de cette obligation

d'isolation et de protection de chaque fil

non utilisé risque d'entraîner des dégâts

matériels.

IMPORTANT: Make all wiring connections in

accordance with the National Electrical Code and

local regulations. Useproper Electrostatic Discharge

(ESD) precautions during installation and servicing

to avoid damaging the electronic circuits of the

actuator.
